Within Lig proteins, the oblong Ig-like domains are organized as multiple repeats of up to 13 homologous domains with only a few amino acids between neighboring domains.
There is also a need for a specialized PCR screening method that is capable of amplifying templates containing multiple repeated sequences, as we and others have found standard Taq reactions unsuitable [8].
The RNAs were allowed to map to multiple locations and therefore a single RNA could be annotated as derived from multiple repeats.
Spectrin repeats are three-helix bundle structures which occur in a large number of diverse proteins, either as single copies or in tandem arrangements of multiple repeats.
Compound eye images are sometimes portrayed as multiple, repeating views of the same object (much like we see the world through a multifaceted prism), but in fact the overall view is formed in the same way as it is in our retina each visual unit contributes to one point in the final image.
Several genes in this region can occur as multiple repeated copies.
Alternatively, Ki-67, which is a very large protein with multiple repeated domains, might function as a scaffold linking together key components at the chromosome periphery.
The MS genesis in tRNA-SINEs is not only involved in complex patterns, such as multiple repeated arrays and length variation in the flanking regions, and is responsible for shorter repeat arrays, but may also explain differences in MS distribution among and within species genomes.
The ancestral condition for eyespot distribution on the wings also contrasts sharply with other, closely studied serially homologous traits such as arthropod limbs and vertebrate teeth, which are more likely to have arisen as multiple repeated units that later become reduced in number and individuated [ 2, 3].
We urge caution in extrapolating our results to school, workplace, or community contexts, or where multiple, repeated exposures may occur, such as in healthcare settings.
